[[Bitcoin emission|Bitcoin emission]] is limited; no more than [[21 Million|21 million]] coins will ever be issued. According to calculations, Bitcoin production will end in [[Bitcoin history|2140]].

| | | | |
| − | Bitcoin transactions and emissions are regulated by an extensive peer-to-peer [[network]]. Bitcoin uses a distributed public universal [[Block chain|database]], spread through a decentralized peer-to-peer network. The network uses digital signatures and is supported by a [[Proof-of-work|proof-of-work]] protocol to ensure [[security]] and legitimacy of funds in use.

| |
| − | To guarantee that a third-party cannot spend a user's bitcoins by issuing false [[Bitcoin transaction|transactions]] in their name, Bitcoin uses [[Bitcoin address|public key cryptography]]. This is a system of digital signatures, in which each person has one or more addresses or wallets, each with an associated pair of public and private keys. A user can sign a transaction with their private key, and the rest of the peers in the network can validate the signature using that user’s public key.
